Hi.
If you feel a folder is a good option for you, then you need to get over the small wheel and beam frame concerns. The most compact useful folders have design because they work. 20" wheels handle great. A folding full sized bike is a bit niche. They only work in certian situations or in a car boot.
See what's available locally before considering a very expensive folder that might not work for you.
Ps it's a great bike, but I don't want one.
